Emil Hvitfeldt has THE comprehensive list of palettes in R https://github.com/EmilHvitfeldt/r-color-palettes

pal.test(viridis)
pal.test(paletteer_c(package = "scico", palette = "davos", n = 111)) # good
pal.test(paletteer_c(package = "scico", palette = "devon", n = 111))
pal.test(paletteer_c(package = "scico", palette = "lapaz", n = 111)) # good
pal.test(paletteer_c(package = "scico", palette = "oslo", n = 111))
pal.test(paletteer_c(package = "scico", palette = "tokyo", n = 111))
pal.test(paletteer_c(package = "scico", palette = "turku", n = 111))
image(penobscot, col=viridis(111))
image(penobscot, col=paletteer_c(package = "scico", palette = "davos", n = 111))
image(penobscot, col=paletteer_c(package = "scico", palette = "lapaz", n = 111))

Add St Helens image as used in plotly? https://github.com/matplotlib/viscm/tree/master/viscm/examples

The 'IsolatedGalaxy' image is a very good test image which can look very different depending on the colormap. http://yt-project.org/doc/visualizing/colormaps/index.html The data is in a mysterious (3D?) format. Perhaps one of these images could be cropped and rasterized and back-transformed from color to numerical value. http://yt-project.org/doc/_images/cmap_imagesProjection_Greys_r.png http://yt-project.org/doc/_images/cmap_imagesProjection_BuPu.png http://yt-project.org/doc/_images/cmap_imagesProjection_Pastels.png http://yt-project.org/doc/_images/cmap_imagesProjection_Pastel2.png

In pal.test, add discrete=TRUE to prevent interpolation
